Extracellular vesicles (EVs) are key in asthma, reflecting molecular differences between type 2 (T2)-high and T2-low asthma. This review highlights EVs as potential biomarkers and therapeutic targets for distinct asthma endotypes.
Area of Science:
- Immunology
- Cell Biology
- Respiratory Medicine
Background:
- Asthma is a complex airway inflammatory disease with identified T2-high and T2-low endotypes.
- Extracellular vesicles (EVs), including exosomes, are crucial for intercellular communication and signaling.
- EVs from various airway cells are implicated in asthma pathogenesis.
Purpose of the Study:
- To review the role of EVs in understanding asthma endotypes.
- To explore EVs as molecular signatures for T2-high and T2-low asthma.
- To identify novel therapeutic targets based on EV functions.
Main Methods:
- Literature review of experimental evidence on EVs in asthma.
- Analysis of studies investigating EV composition and function in different asthma endotypes.
- Synthesis of current knowledge on EV-mediated intercellular communication in asthma.
Main Results:
- EVs secreted by diverse cell types (eosinophils, mast cells, etc.) modulate asthma.
- EVs can reflect the distinct molecular profiles of T2-high and T2-low asthma.
- EVs offer insights into disease mechanisms and potential therapeutic strategies.
Conclusions:
- EVs play a significant role in asthma pathobiology and endotype differentiation.
- Profiling EVs may aid in diagnosing and classifying asthma subtypes.
- Targeting EVs presents a promising avenue for novel asthma therapies.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
